One thing I have noticed is that when a dem is in office it becomes much easier to tell who your comrades are.
I do think the trump era did move a lot of people left, but in the end we all saw how so many radlibs just went back to brunch once Biden was elected. If someone’s opposing a dem while that dem is in office, I think there’s a much greater chance that person is committed to some sort of leftism. With a republican president we just get liberals with radical aesthetic, like “the resistance.” Sort of dumb reason to be pro-dem but just something I’ve noticed lately.
